That is testing brass against the screen. An EXTREMELY soft metal. The only test that had any validity was the key dropping because it gave the keyRING(the only steel part) a small chance to hit the screen.
Edit: Even the nickel coating on some keys is softer than window glass.... so that key test was totally useless.

according to this scale, only hardened steel or iron would scratch the glass, as well as some more rare minerals, (ruby, diamond, etc).
Mohs scale of mineral hardness - Wikipedia, the free encyclopedia
Did you even read my post? It doesn't matter if you carry around stone tools. If one tiny piece of grit gets between the screen and something else. Say hello to your new/scratch. And jkayner, I'm pretty sure granite and quartz are on that list and they're very common

How common are granite and quartz in your pocket? I mean come on, most people just have their keys in their pocket and that's the hardest/sharpest thing they have with them. Clearly keys don't do any damage and normally keyrings are rounded, even on the end part.
Check out my Droid Ultra FAQ!
I have had 4 storms and I NEVER scratched any of them. I have dropped them on asphalt and in sandy gritty driveways face down and I have ZERO scratches.
You're much better off saving your money than buying a 5-10 dollar "screen saver" and then obsessing about the corners that "look dirty" or "might peel soon"
Enjoy the phone, save your money you won't scratch it
